Casascius coins are physical coins with embedded
Bitcoin value. They were created by Mike Caldwell as a novel way to store and gift Bitcoins. Each coin is made of brass, gold-plated, and features a hologram and tamper-resistant sticker to ensure authenticity. The private key, necessary to access the Bitcoin value, is hidden under the hologram and can only be revealed by peeling it off, a process which cannot be undone. This unique combination of physical and digital security features makes Casascius coins a sought-after collector's item in the Bitcoin community.
